CAR-WHEEL.

I Application led December 29, 1900. Serial No. 41,450. (No model.)

To aLZZ whom it may concern.-

Beit known that I, CONSTANTINE B. VOY- NOW, a citizen of the United States. residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in' Car-Wheels, of which the following is a specification. j

My invention has relation to a car-wheel of the type or class wherein the rim or tire and of two diiere'nt 'or ,the same metals and afterward assembled together, and in such oo nnection it relates to the-construction and arrangement of such a car-wheel.

The principal objects of my invention are, irst, to provide a carl-wheel in which the tire orrim can be readily applied and secured to i or removed from the body`or core of the wheel, as requirements demand; second, to

provide a car-wheel in which the tire or rim j is held in position on the body or core by side elevational view of a portion ofthe tireA means of a suitable material introduced or placed between the rim or tire and the body or core, and, third, to provide a car-wheel in which the tire or rim and the `body or core are so arranged that when assembled a space is provided between the body or core and the rim orV tire adapted for the reception and retention of a suitable material to form abcd or filler, which is maintained in said space by the configuration or shape of the space.

The nature and scope of my invention will be morefully understood from the following description, taken in connection with the accompanying drawings, forming part hereof,

in whichl v Figure 1 is a side elevational view of a carwheel embodying my invention. Fig. 2 is an enlarged vertical central sectional view of the tire or rim and of a portion of the body.

or core of the wheel. Fig.. 3 is an 'enlarged or rim and body or core of a wheel embodying a modified form of the invention. Fig. 4. is a cross-sectional view on the, line a: of Fig. 3. Fig. 5 is an enlarged side elevational view of a portion of a car-wheel embodying a 'still further modified form of my invention,

and Fig. 6 is a cross-sectional view on the line'yfg ofFig. 5. l 4

Referring to the drawings, a represents the rim or tire of' the Wheel, and b the body or j core thereof.` In Figs. l and 2the rim or tire a. at its inner periphery is preferably of slightly-greater diameter than the outer pe ri phery of the body or core b. The inner periphery of the tire a is step-shaped-that is, it-alternately projects outward and inward, as at o.2 and as, respectively-while the body b is correspondingly shaped, as at b2 and b3; but the projections and indentationsam reversely arranged, so that an outer projection a2 of the tire or rim is arranged opposite to an inner projection or indentation bs of the body or core. The inner periphery of the rim or tire o. and the outer periphery of the body or core b are also peripherally grooved, the grooves being complementally arranged to forma relatively wide substantially annular' space between the faces of the wheel, and this wide space communicates with the smaller substantially annular spaces at either face of the wheel, which smaller spaces result from v making the inner diameter of the rim or tire a greater than the diameter of the body or core b. Thewide space and the smaller spaces are j adapted to be filled by a bed or filler of suitable material-such as zinc,typemetal sulfur, or the like-so that there will be confined between the rim or tire and the body or core a relatively large band d of the bed or ller, narrowing down at either face into a relatively small band d or d2 of said bed or filler.

The projections a2 a and b? VbE and the corre` spondingly-shaped bands of filler serve to prevent the turning of the rim or tire on the' body or'core ofthe Wheel under tracti le strain. 4The bed or filler also serves to interlock the rim or tire a and body or core b to prevent separation under torsional strain or side thrust In Figs. 3 and 4 the construction is somewhat modified by making the outer projec.`

tions Z112 of the.body or Acore b of a width or thickness in cross-section slightly less than the width or thickness of the channel or space in the inwardly-projecting portions 0.12 ofthe rim or tire, thus permitting the bodyor c'ore b to be first arranged so that the steps of the body or core enter the indentations ofthe rim or tire and then to be turned so that said projections b12 may partially ,enter the channel or space of the projections al* of the rim or tire, as clearly illustrated in Fig. 43.

IOO

In'Figs. 5 and 6, instead of interlocking the rim or tire and the body or core by means of the step-like co'mplemental portionslol,2 and as and b2 and b3, the'channeledportions are annular, and at intervals radial channels are drilled through the body and into the rim or ltire, so that when the bed or filler enters the channels or spaces it [ills up these channels or spaces 'and forms plugs or keys d",of metal,

which prevent the separation of the rim or tire from the body or core under tractile strain or side thrust. A material or materials may be used as a bed or iiller, which i's or aresusceptible of wholly or partially assimilating or combining with the material or materials 'of the rim or tireand body or core of thewheel,

so as to make,y as it were, an integral wheel, but at the same vtime capable under treatv ment, such as fusion or otherwise, to cause the'assimilating or combining element of the wh` el to be yreadily separable to part the tire or rifm from the bodyor core. of the wheel.

Itis manifestly obvious that modifications v as todetailsfmaybemade inv both the shape or form` of the rim or tire and body or core in sofar as such a wheel has been illustrated in the drawings `of my invention without debody orcore and abcd or filler 4introducedv rial of alowermelting-point thaneither the parting from the scope of the same, an d hence v nletal of said rimertire or of the bodyfor core,

4. A car-wheel, comprising a rim or tire, 7o the inner periphery of which is channeled or' grooved, 'a body or core, the periphery whereof is channeled or grooved complementally to the rim or tire,` thediarneter of said body or core being less than the-inner diameterof the rim or tire, and a bed or -filler in-` terposed between fand completely separating the contiguous peripheries of thev rim or tire andbody or core and confined in the space formed by the com'plemental channels or 8o grooves of said rim or tire and body or core',

the said bed-or filler consisting of a material of a lower fusing-pointthan the metal of said rim or tire and body or core and said bed or filler neither fusing nor welding with said rim i or tire or body or core.

5. A car-wheel, comprising a'rim'or tire,` a body or. core, the diameter', of which is less than the innerdiameter of said rim or tire, a
